Abstract: A smoker's accessory for filtering sidestream smoke emitted from a burning cigarette comprises an exhaust fan mounted in a central unit and a sidestream smoke filter cartridge having a cigarette tube for a burning cigarette, is placed is provided alongside the central component. The filter cartridge is provided in a housing which is connected to the central fan support. The cigarette tube is as long as a cigarette and has a diameter of at least 1.5 times the diameter of the cigarette. A porous low pressure drop filter element is provided at the end of the cigarette tube for removing sidestream smoke. The housing has a front end wall in which the cigarette holder with the cigarette to be positioned. A fresh air inlet is provided which permits the fan to draw fresh air inside the cigarette tube along the cigarette and pick up the sidestream smoke from the lit cigarette for purposes of drawing through the filter cartridge before release to the surroundings. The smoker's accessory may optionally be provided with an exhale filter so that both sidestream smoke and exhale smoke is filtered before release to the surroundings. The filters are high efficient, low pressure drop filters which ensure there is minimal, if any, detectable traces of cigarette smoke released to the surroundings.

The second shaft revolves about the bearings placed on each side of the second gearwheel. At least one spring is fitted to act with a force upon an outer race of rolling members of one of the bearings. A glide fitting is provided between a circumferential face of the outer race and the gear frame or a connected part. The force effect applied by the spring(s) is transferred through the rolling members of the bearing to the inner race of the bearing and further to the other bearing placed at the opposite side of the gearwheel whereby the play in both bearings between the rolling members and the bearing races is eliminated.

Title: Drying oven, for bricks - comprising separate, linked drying chambers connected to heat exchangers
IPC: F26B21/02
Filed: 1976-06-30
Granted: 1985-03-25
Abstract: Dryer, esp. for bricks, comprises at least two separate indirectly heated drying chambers separated by thermal insulation from each other and from the outside. It includes two heat exchanger devices the first communicating with the first drying chamber at a higher temp. This is supplied with hot moist unsatd. air from the drying chamber and acts to reduce the temp. of the hot moist air to a level at which it becomes saturated with water vapour. The second heat exchanger is situated inside the second drying chamber and in series with the first drying chamber and is fed with the hot satd. air leaving the chamber. Heat exchanger is provided with a mechanism for removing the water. condensing inside it and passing it back to the first drying chamber, returning it to the satd. air fed in there. The heat contained in the water is passed back to the first drying chamber, so that lower energy consumption is required. The temp. and the humidity in each drying chamber can vary within wide limits.

Title: Filtering-draining-insulating mattress suitable for lining the internal surfaces of silos, when the latter are built to contain sodium chloride or other chlorides, to be kept fluid so as to be able to be handled at any time
Inventor: BELLUATI GIUSEPPE
IPC: A47C/
Filed: 1990-04-27
Granted: 1994-11-05
Abstract: The object of the present invention is a new means which, although made up of elements that are known and used for other embodiments and for other purposes, is suitable for reducing or even eliminating the presence of moisture in silos, where in particular sodium chloride (NaCl), used principally for controlling and rectifying the situations which arise along roads and motorways during the winter months, and when snow falls on them or a layer of ice forms on them, is stored and kept. Said means, made up of a mattress of geotextile material, is used for the internal covering or lining of the silos, especially those made of metal, built to contain said chlorides, which, as is well-known, are highly hygroscopic and easily packable products and can therefore create great difficulties when the flow thereof is hindered by deposits and bridges which form in the interior and on the internal walls of said silos.

Inventor: CAMOSSI ROBERTO
IPC: B30B15/00
Filed: 1988-05-31
Granted: 1990-06-15
Abstract: The present invention concerns a mechanical, low-noise press, particularly of the screw type, comprising a tup-bearing ram (12, 28) connected with a driving screw (13, 24), rotatingly connected with a lead nut (14, 21-23), which is integrally fixed on the frame supporting the press (10). The press also comprises sealing means (18, 19, 30) which define, together with the mating surfaces of the screw and of the lead nut, at least one chamber (16, 31), having a pre-determined volume, adapted to collect an incompressible medium, such as lubricating oil, and circulation means (16, 17, 19, 20) in order to maintain within said chamber a controlled delivery of the medium. Such delivery insures the presence of a constant spacing film of medium between the mating surfaces during the operation phases of the press, so as to prevent, during such phases, the direct contact between the screw and the lead nut, thereby absorbing the vibrations and the collisions generated by their interaction.
